Witold's Report, also known as Pilecki's Report, was an official report
that was prepared in 1943 by Witold Pilecki, a soldier in the Polish
Army and a secret agent of the Polish resistance, who entered and
escaped from the Auschwitz concentration camp. It was the world's first
record of the Holocaust. Starting in November 1940, the first
information about the genocide that was occurring in the camp was sent
via ZOW to Home Army Headquarters in Warsaw.From March 1941 Witold
Pilecki's reports were forwarded to the Polish government in exile and
through it, to the British government in London and other Allied
governments. These reports informed the Allies about the Holocaust and
were the principal source of intelligence on Auschwitz-Birkenau for the
Western Allies The first publication of Witold's Report took place in 2000, 55 years after the war.
